Johannes Kepler said that IF the planetary orbits are elliptical,

THEN that would explain the measurements that Tycho Brahe

spent his whole life collecting.

Isaac Newton said that IF gravity works the way he thought it does,

THEN the planetary orbits have to be elliptical.

But neither Kepler nor Newton could ever say that the orbits are REALLY ellipses.

Both of their statements are 'only theories', just like the theory of evolution.

They have never been proven.

Did Johannes Kepler discover Kepler planets?

No, Johannes Kepler is best known for describing the laws that dictate how orbits work. The Kepler planets were discovered by the Kepler telescope, a spacecraft named in his honor.
